Bio: When she was young she knew she was destined to be the next ruler alongside Starshine after her mom retires but after Galaxy’s birth, Twilight declared that Galaxy is gonna rule alongside Starshine after Twilight retires. From then on Estrella started to dislike Galaxy and wanted revenge on Galaxy and Twilight. After Cozy, Tirek and Chrysalis’s defeat and reformation, Estrella realized that revenge was not the answer to any problem and vowed that she’d be a royal guard and protect her sisters when they rule.  
Side notes:  
~Her middle part of the eye(pupil) is not pure black because she got a little blind after casting a spell on her self.  
~She was not like this before. She was one of the beautiful girl in her family but after she casted a spell on her, her physical appearance changed and started to look like what it is now.  
~She loves Starshine more than Galaxy because when Galaxy was born, Twilight declared that Galaxy will rule alongside Starshine instead of Estrella.  
~She doesn’t have any friends “yet”
